Function delete 

fn delete(id: &str) -> Value

A conversation deleted in Sioul (23 October 2026): Sioul is never the phone’s SMS app (it asks no SMS role, docs/texts.md), so Android lets it delete nothing from the phone’s provider. Its texts until now leave Sioul on every device (a sealed mark; the phone writes its log again without them, so every computer’s copy follows); the phone’s own texting app keeps them. A text that comes later starts it again.
